The NCP59302 is designed to operate with voltage is set by the ratio of two external resistors as shown ceramic output capacitors. The recommended output in Figure 21. capacitance value is 47 (cid:2)F or greater. Such capacitors help The device maintains the voltage at the ADJ pin at 1.24 V to improve transient response and noise reduction at high referenced to ground. The current in R2 is then equal to frequency. 1.24 V / R2, and the current in R1 is the current in R2 plus the ADJ pin bias current. The ADJ pin bias current flows Input Capacitor from V through R1 into the ADJ pin. An input capacitor of 1.0 (cid:2)F or greater is recommended OUT The output voltage can be calculated using the formula when the device is more than 4 inches away from the bulk shown in Figure 21. supply capacitance, or when the supply is a battery. Small, surface−mount chip capacitors can be used for the NCP59302 VIN VOUT bypassing. The capacitor should be place within 1 inch of VIN VOUT the device for optimal performance.
